Fanny Paelinck-Horgnies was a Belgian painter of German origin, known for her works in religious painting, portraiture, history painting, genre scenes and mythological scenes. Her style can be compared to neo-classicism.

Louise Thérèse Françoise Élisabeth Horgnies was born in Regensburg on 1 May 1805. Fanny Horgnies worked in Brussels. Her paintings fall mainly under history paintings, religious scenes and genre scenes, but later she also focused on romantic subjects.

Her career as a painter began around 1820 as a student of Joseph Paelinck, whom she married in Brussels on 15 October 1827. According to the art historian and artist Alexia Creusen, her marriage did not put an end to her artistic career, unlike the majority of woman painters of her time.

Paelinck-Horgnies summarized her career as an artist as follows in a letter addressed to A.P. Sunaert, the compiler of the Ghent museum catalog: "My brief career as an artist has been so mediocre, that it is really impossible that you would want to know the name of the author who sends one of my paintings: I would be very grateful if you would not mention me in a catalog, be, by all means, infinitely grateful to you for the honor you have bestowed on me in this circumstance."

She died in Brussels on 9 February 1887.
